A Climax locomotive is a type of geared steam locomotive built by the Climax Manufacturing Company (later renamed to the Climax Locomotive Works), of Corry, Pennsylvania. These had two steam cylinders attached to a transmission located under the center of the boiler, which sent power to driveshafts running to the front and rear trucks. Some 1,000-1,100 were built in three classes (A, B, and C) between 1888 and 1928.
